Syndra has a lot of single target burst damage. Since her E and R are counted as projectiles, you can Block them with Wind Wall to prevent being bursted down.

Generally you should win this fight, but you need to pay attention to her positioning and where her balls are so you can avoid the stun. Avoid using your windwall until she ults you. Overall you have to react fast and just know positioning.
